Title: Production of high purity nickel aqueous solution
Inventor: IMAMURA MASAKI
IPC: C22B3/20
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a high purity nickel aq. solution by removing zinc and iron from a zinc-and iron-containing nickel aq. solution. SOLUTION: The high purity nickel aq. solution is recovered by adding a oxidizing agent and a neutralizer into an acidic nickel aq. solution containing zinc and iron as impurities, such as a nickel raw material solution, to increase the pH to remove zinc with iron as a deposit. On the other hand, nickel in the deposit is dissolved and recovered in an acid cleaning liquid by cleaning the deposit with an acidic solution and after the resultant acid cleaning liquid is brought into contact with an alkyl phosphonic ester to extract zinc in the acid cleaning liquid, the acid cleaning liquid is returned to the nickel raw material solution. In such a case, the alkyl phosphonic ester used as the extractant is preferably 2-ethylhexyl phosphonic mono-2-ethylhexyl ester and it is effective when the resultant high purity nickel aq. solution is a nickel sulfate aq. solution.

Title: Gear drive device
Inventor: TAKEMOTO TAKESHI
IPC: F16H1/06
Filed: 1981-03-17
Abstract: PURPOSE:To lessen backlash and reduce wear of teeth of a gear by providing each gear with a cylinder which are united in a body and brought into engagement by pressing means. CONSTITUTION:A drive gear 6 and a reduction gear 7 are provided with cylinders 16, 18 concentric with the gears 6, 7, the sum of each radius of which is the sum of each pitch radius of the gears 6, 7 which engage each other. A leaf spring 20 is adapted to press one gear against the other gear to engage each other. When the drive gear 6 and the reduction gear 7 are rotated, smoothness of such rotation is ensured, resisting the leaf spring 20, but when the gears 6, 7 are stopped, pressure force of the leaf spring 20 causes cylindrical surfaces 15, 17 of the cylinders 16, 18 to contact each other, resulting in that the distance between a motor shaft 5 and a support shaft 8 is the sum of each pitch radius of the gears 6, 7. Accordingly, backlash is produced only by dimensions error between pitch circles of the drive gear 6 and the reduction gear 7 and the cylindrical surfaces 15, 17.

Title: Multistage rolling mill
Inventor: TAKUBO YUKIYASU
IPC: B21B13/14
Filed: 1980-03-28
Abstract: PURPOSE: To prevent the roll chock from being loaded with the bending moment, by making the beam and the backup roll jointly movable in the horizontal direction, and by moving the end of the drum of the backup roll to a suitable position corresponding to the breadth of the rolled material.  
     CONSTITUTION: The beams 10, 13 are arranged respectively between the backup roll chocks 5, 6 and the roll's vertical position adjuster 11, and between the backup roll chocks 8, 9 and the roll's vertical position adjuster 15; the movers 21, 23 are respectively connected with the beams 13, 10 so as to be movable in the vertical direction but immovable in the direction of roll axes. The movers 21, 23 move the beams 10, 13 and the backup rolls 4, 7 jointly in the direction of roll axes correspondingly to the breadth of the rolled material. These movements generate a rolling load which is transmitted from the chocks 8, 9, 5, 6, through the beams 10, 13 to the roll's vertical position adjusters 11, 15 so that the distance between the loading points does not generate any eccentric bearing load. Besides, since the beams 10, 13 are respectively provided with the thrust blocks 10' and 13', the roll chocks 8, 9, 5, 6 sufficiently endure the bending moment owing to the distance between the loading points.

Abstract: PURPOSE:To inexpensively lower the lower limit particle size to be measured to <=1/3 the lower limit particle size of the prior art by providing a light source part where a deuterium or halogen lamp, interference filter and pinhole are used as well as a semiconductor sensor and image intensifier. CONSTITUTION:The lower limit particle size to be measured is smaller as the wavelength of light for measurement is shorter in the case of using a forward microangle scattering method. The need for a UV laser which is costly and has poor maintenance characteristic is, therefore, eliminated by using the deuterium lamp or halogen lamp as the light source lamp 1, using the interference filter 3 to obtain light of a single wavelength and imparting convergence to the light by the pinhole 4; in addition, the quantity of light is amplified by the image intensifier 7 provided on the photodetecting surface side of the semiconductor photosensor 8, by which the quantity of the light equiv. to the quantity of the light obtainable with the conventional gaseous He-Ne laser light source is obtd. and the lower limit particle size to be measured is lowered to <=1/3. Moreover, the measurement range is largely expanded by exchange of the filter 3.

Title: Method of polishing surface of aluminum wheel
Inventor: FUJINO KIYOSHI
IPC: B24B1/00
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To surely and easily remove a pinhole by dipping a casted material of aluminum wheel in a chemical composed mainly of caustic soda, fusing the surface of the material, and removing pinholes formed on the material surface in casting. SOLUTION: When a casting such as aluminum wheel is formed by use of a vertical squeeze casting machine and a metal mold, it is dipped in a caustic soda solution after thermal treatment, and the surface is fused to eliminate pinholes. It is then washed with water to remove the chemical followed by machining to ensure the dimensional precision. Then, polishing is performed, for example, by buffing of about 0.05-0.15mm to impart the gloss to the surface. Finally, coating or plating is performed to prevent corrosion. Consequently, the buffing time can be also significantly shortened.

Abstract: PURPOSE:To obtain a waveguide having a wide operating frequency by fitting a coaxial line at a right angle to a circular or nearly square waveguide and making its guide axis coincident with one polarized plane. CONSTITUTION:The polarized wave E3 entering from a waveguide inlet B is coincident with that of a guide axis of a coaxial line 2 and that of other polarized wave E1 is orthogonal to the guide axis in case of a circular waveguide circuit.

Abstract: PURPOSE:To make possible fine control on the mixing ratio of shot grain, jetted from a spray gun, to air. CONSTITUTION:A shot blasting device has a fan 24f for blowing shot grain 2 up into the internal space of a case 24 while being capable of adjusting the blow-up quantity; and a material supply pipeline 25 with one end thereof opened into the internal space of the case 24 and with the other end thereof connected to a spray gun 26. Resistance at the time of the shot grain 2 being sucked into the spray gun 26 therefore becomes extremely small, and only the quantity corresponding to negative pressure is sucked smoothly even in the case of reducing the air flow flowing in the spray gun 26. The mixture ratio of the jetted shot grain to air can be also controlled by adjusting the blown-up quantity of the shot grain 2 by the fan 24f.
